SPRAYING APPARATUS.

SPECIF-IGATION forming part of Letters Patent No. 716,910, dated December 30, 1902.

Application filed May 14,1902. Serial No. 107,288. (No model) To all whom t may concern:

Be it known that I, THEoDoR WILHELM LBBECKE, a subject of the German Emperor, and a resident of Hamburg, in the German ful Improvements in Spraying Apparatus, of which the following is a specification.

The present invention relates to-spraying apparatus for disinfecting purposes of that class in which the disinfectingliquid is forced in the form of a jet or spray against the object or objects to be disinfected by the action ot' a piston slidably arranged within a suitable vessel provided at one end with a suitable inlet for filling in the disinfectiug liquid and a suitable outlet for attaching a hose, carrying at its free end a nozzle or' sprayhead and provided at the other end with a suitable inlet for the pressure medium (pressure-Water, steam, compressed air, die.) operating the piston, the said pist-on separating the disinfecting liquid from the pressure medium, so that the strength or degree of concentration of the former remains unchanged or unaltered when it is forced out of the vessel by the forward stroke of the piston.

My invention more particularly refers toV a controllable pipe connection between the pressure-medium conduit and the space of the vessel destined for the reception ot' the disinfecting liquid. After the proper connections have been established the said connectingpipe allows of admitting the pressure medium into the disinfectant-space of the vesselthat is to say, at the other side 0fthe pistonin order to eiect the return stroke ofthe lat- The said connecting-pipe also permits of an addition of the pressure medium (water, steam, Che.) to the disinfectant in the disinfectant-space of the vessel,provide'd such addition is desired or required.

In the accompanying drawings, Figure l shows a vertical central section of a disinfectant-spraying apparatus constructed in accordance with and embodying my invention. pressure-medium conduit and of the hose through which the disinfecting liquid is ejectedor forced out are in the positions they oc-` cupy when the apparatus is at Work.

of the pressure-medium conduit, showing the The stop-valves or stop-cocks of the l similar sectional view showing the said stopcock p in the position to allow the pressure medium to enter into the auxiliary pipe, but to bar the pressure medium from entering into the main vessel or from its action upon the piston, respectively.

Similar letters referto similar parts throughout the several views.

My improved apparatus comprises a large but preferably transportable vessel a, which is closed with the exception of an inlet b at its lower portion, and an outlet 7c and a fillinginlet d, provided with a closing device CZ' and filling-cup d! at its upper portion. This vessel is cylindrical and contains a pistou e, for

the guidance of which a central iixed tubef 7o Vpipe or hose g, of small diameter, which ter- V'stand-pipe.

minates in a nozzle or spray-head. (Not shown.) The inlet b inthe lower portion of the vessel a ls provided with a hose h', whereby it may be connected, for example, to a water In the bottom of the vessel a is also arranged a suitable valve or cock c' for -drawing ott the exhausted pressure medium.

In the inlet-neck b is mounted a suitable multiple-way cock. Nhen the plug b' of this cock is in the position shown by Fig. l, the pressure medium is allowed to flow or enter into the main vessel os. When the plug b' is in the position Fig. 2, pressure medium is cut off, and when the plug b is in the position Fig. 3 the connection is thus that the pressure medium is enabled to enter into the tube f. The upper end of this tube f, passing through the top of the vessel a,-may be brought by means of a three-Way cock (intercalated between the outlet It, the hose g, and the tube f) into communication with the interior of the vesselor with the hose, or may be cut o from either, this latter position being` shown in Fig. l.

When it is desired to use the apparatus, it is filled through the filling device d CZ d2 with the disinfecting liquid-for example, carbolic acid-above the piston e,by,which means the piston is depressed. The hose h is then connected with the pressure water conduit andthe cock Z9 opened, so thatthe pressurethe admission of the water rushes into the vessel a. and presses against4 the piston e, gradually lifting it and forcing the disinfecting liquid out through the hose g and its nozzle in the form of a line jet or spray. The operative has only to direct the spray from the hose g or its nozzle, respectively, against the object or surface to be disinfected. The disinfecting liquid is always separated from the water under pressure by the piston e, so that the strength or degrec of concentration of the disinfecting liquid remains unaltered. Steam or compressed air may, if desired, be employed instead of water under pressure for spraying the disinfectant. After the disinfecting liquid has been forced out of the vessel ct the piston eis at the end of its upward or forward stroke. To again bring down the piston into its original position, the cock c is to be turned so as to connect the tube f with the inlet 7c, the cock b' is to be brought from the position Fig. l into the position Fig. 3, and the drawoff cock t' opened. The water under pressure entering now into the upper part of the Vessel and pressing from above against the piston moves the latter down, While the exhausted pressure-water is forced out through the draw-off cock t'. Thereupon the cock c is turned back in the position Fig. l and the cock t' closed again. The vessel-that is to say, the space above the piston--is now filled with Water, to which the required quantity of the disinfectant may be added or mixed through the lling device d d d2. Thus the production of the disinfecting liquid proper in separate mixing vessels is avoided, as the vessel a and the cup d2 can be used as measuring Vessels.

When direct connection is made between the tube f and the hose g, by turning the cock c accordingly, and the cock b is brought into the position Fig. 3, the pressure mediumfor example, water or steam-may be forced directly through the hose g.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is-

l. In apparatus such as described, the combination with a vessel, means for supplying a disinfectant thereto and means for supplying a liquid from a suitable source of supply to the vessel; of means for forcing the contents therefrom by liquid from said source of supply and preventing the admixture of the forcing liquid with said contents, for the purpose set forth.

2. In apparatus such as described, the combination with a vessel, a feed-pipe and a measuring device connected thereto and of a capacity proportionate to the capacity of said vessel and means for supplying aliquid from a suitable source of supply to said vessel; of means for forcing the contents therefrom by liquid from the said source of supply and preventing the admixture of the forcing liquid with said contents of the vessel, for the purpose set forth.

3. Apparatus such as'described, comprising a vessel, a piston therein, means for supplying a disinfecting liquid to the vessel on one side of the piston, a pipe connected to said vessel on said side of the piston, means for admitting a fluid under pressure -to the vessel on the opposite side of said piston and a valved exhaust-pipe connected to the Vessel on the last-named side of the` piston; in combination with means for admitting pressure fluid from one side of the piston to its opposite side, for the purpose set forth.
